To alliwhom it may concern,.- .i i i Y. i n Be it known thatl, LEwIs W."CONNELL, a citizen of the United States,V residing in Joliet, i in the`county of Willand `State ofl Illinois,` have` invented a new and useful` Improvement! in `Barb-Fence-VVire yl\[a,ch,ines, of whit-lathe following is aspecication. f` y i .Thisinvention relates to barbed fencefw'ire machines, and more particularly to machines for .makingthat kind lof barbedgfencewire wherein but a single strandisemployed, the wire` barbs coiled about it being4 heldin place by short kinks or bends, formed in the attached. f i

. The object of my inventionlis to produce an automatic machine of a simple and durable.

`construction for rapidly manufacturingsuch `fence-wire, and particularly` such fence-wire as I have shownin thefaccompanying drawings at Fig. 22,'y the same being ,also patented in Letters Patent No.303,406dated August 12,1884.

Machines have heretofore been, made for .manufacturing this fence-Wire,: asshown .in the Reissned Letters `Patent,1\To..10,59,7 of May 12, 1885, -in whichv machines the-kink or bend is first formed in the fence-strand by suitable dies, when the strand isefed forward into position for the coiling-head andthe barb then?` `wrapped about the strand at'the'kink or bend therein. To do good'work 4these machines .obviously'requireextreme accuracy in the feeding mechanism of the fence-strand, else the barbswill 'not be properly appliedatthe kinks. In my-invention the kink is.no`t formed inv the fence-strand until afterthe barb has been coiled thereon. The barblis cut off before being coiled around thefence-` wire, and both its ends are wrapped at once `in opposite directions around the strand-wire by two oppositely-revolvingcoiling heads or fingers.- VThe fence-strand as well as the barb.

vis held in positionwhile the latter is being .Wrapped around the former by the 4crimping dies orjaws. After the barb is coiledaround the fence-strand a further movement ofthe dies forms the kink or crimp in the fencestrand. To still further increase the capacity of the machine, two barbs are" applied at once. This is accomplished by means of three one of thezcoiling-iingers.

shows the 'barbed `fence-wire the.` machine` is specially designed to make. fFig. 23 is a detail view showing the mechanism for rotating .the feed-wheel shaft.

In said drawings, A represents the frame of the machine,` a thefence wire or strand which is to be barbed, and a' a the two barbwires from which the barbs are c ut. Each of these wires is supplied from a suitable spool, (notshown in the drawings,)and the finished -product or barbed wire a' is-wound upon a `suitable spool, A, at one end of the machine.

Thefence-wire a is fed or drawn through the` machine intermittently by means of an interymittently-revolving feedfwheel, B, on theshaft B. This feed-wheel has radial forked arms b, .-which carry or support the strand a, and also radial clamping jaws orarms b and b2, the .arms b2 being pivotedl to the cast or` rigid arms b"at b3,so as to clamp the strand a between them and pullor feed it forward a certain distance at each movement of theshaft coilingheada the middle one havingacoilwhich form l ICO B' and its wheel B. The arms or jaws bz are operated to clamp and release the wire a as the wheel B revolves by means of a fixed cam, b", in the form of a collar surrounding the shaft B', against which the inner ends of the arms b2 impinge as they revolve around with the wheel B. The ends of the arms b2 are provided with friction rollers or wheels b5, to bear against the face of the cam. The arms or jaws b'Z may be pressed open when not closed by the cam by means of springs, which may be attached by suitable screws to the wheel B 5 but these springs need not be used. The cam or collar b4 is prevented from. turning with the shaft B' by the bracket bs, attached to the frame, and to which the sleeve of the collar b4 is attached by the set-screw b". By turning the sleeve of the cam b4 in the collar bm of the b-racket be, the face of the cam may be adjusted to open and close the jaws b2 at the proper points. The wheel B has four pairs of arms, bV b2, and it or its shaft B' is revolved intermittently a quarter-turn each time by means of the ratchet B2, secured to said shaft, and the pawl B3, pivoted to and between the arms B, which are mounted loosely on the shaft B', and are swung back and fort-h by the pitman-rod B5, connected to the revolving crank BG. A spring, Bl, serves to press the pawl B3 against the teeth of the ratchet B2. The shaft B8, to which the crank B6 is secured, is driven from the main drivingshaft C through the bevelgears C' C2. of the barb-wires a' is fed diagonally across the fence-wire a by means of a pivoted feedlever D, having two clamping-jaws, d and d', on its upper end, thelatter pivoted to the former at d2. The levers D are vibrated back and forth on their pivots D' by means of the links d3, which are pivoted at one end to the pivotal jaws d', and at the other to the levers ct. The levers d* are pivoted at d5 to the frame A, and are connected at their lower ends to the two branches d6 of the yoke-lever d7 by the piv-' otal links ds. The upper end ofthe yoke-lever d7 has a pin or roller, d, which `tits in the grooved cam d10 on the driving-shaft C. As

the links d3, by which the power is communicated to the feed-levers D, are pivoted directly to the movable jaws d', these jaws will be opened and release the wires a' when the levers D are pulled back by the links d3, and elosed to clamp the wires a' and feed them forward when the levers D are pushed forward. The pivoted jaws d' are each provided .with a fiange, d, and set-screw d, by means of which the amount of slack motion may be .regulated and the feed adjusted to the length of barb required. As the levers d4 and the yoke or branched levers d (17 vibrate in planes at an angle to each other, the links d8 connecting them are provided with pins d, which tit in eyes t on the levers, to permit the links to swivel properly. The `barb-wires a' are each cut olf at suitable lengths to form barbs by knives E and E', the former being astationary one and fixed to the frame of the ma- Each chine, and the latter a reciprocating or movable one. The cutting faces or edges of the knives are set at an angle to the direction of the wires a', so as topoint the barbs at the same ti'ne they are severed. The movable knives E', one for each barb wire et', are rigidly secured in the head F of the lever F', by which said knives are operated. The lever F' and a similar lever, F2, are pivoted to the frame on the shaft or pinf, and the two levers are vibrated, to give the, requisite movements to the tool-heads F and F3 thereon, by V,the cams f' and f2 on the driving-shaft C. rIhese cams are grooved cams, and the levers F' and F2 are provided with pins or frictionrollers to fit in the grooves. .lhe crimpingdies G and H have severally sliding parts g It, which tit in suitable grooves in the parts G H, so that the parts g h may move independently of the dies G H. The die-pieces G and H tit in suitable holes 'or grooves cast or otherwise formed in the heads F and F3, and their ends abut against the ends of the hollow screwplugs G' H', securely fixed in the heads F F3,A

so that the dies G H can withstand the requisite pressure to form the crimps a2 in the fencewire. The movable piece or slide g of the die G extends up through the hollow plug G', 'and its upper end abuts against the adjustable stop or screw g', securelyiixed in an arm or projection, g2, on the head F. A

spring, g3, is interposed between the stop g' and the sliding clamp-bar g, so as to force the clamp or slide g down. This spring should be a hat spring, and it may be secured to an arm or projection, g4, on the head F. The movable piece or slide h ofthe die H in like mannerextends down through" the hollow screw-plug H', and it is connected at its lower end with a pivoted arm, h', having a spring, h2, which serves to force the slide /L up, so as to clamp the fence-strand and barb between itself and the opposing clamp or slide g.V The two slides h h are connected together at their lower 4ends by a cross bar or pin, h3, so that both of them may be operated by a single spring lever or arm, h', the end of said lever being forked and' fitting over this pin h3. A fixed stop, h4, limits the upward movementot' this lever or arm h'. A pivoted stop or cam, h5, provided with a spring, h6, to keep it in position, is inserted between the head F3 and the arm h' to withdraw the slides h with the dies H. As the lever F2 swings the head F3 around on its pivot, the pawl or cam h5 slips off the 'shoulder hl andlpermits the spring if to force,

up'the slide h. As the head F3 makes its upward stroke, the spring-arm h and the slide It, Aactuated thereby,will follow up, and as at this time the pivoted stop or cam h5 is slipped off or by the flat shoulder hl the slide h willbe forced farther up than the die H, so as to project beyond it and clamp and hold the barb while it is being cut off and coiled around the fence-wire. When the head F3v makes its further upward stroke to cause the die H to form the crimp in the fence-wire, the further IIS upward movement of the arm It being arrested -by the stop h", so that theipivoted stop or cam h can pass over the projection hl, the spring h6 then restores said cam h5 to its position, as shown in Fig. 4, so that when the head F3` 4 makes its downstroke the slide h will be with- `tion.

K, have large central openings,las shown in Figs. 11 or 14, soV that barbs, after'being se-y cured to the wire a, can pass through them. 'lhelclamps o`r slides g and h serve to support? "Patent No. 303,406.

drawn with the die H. l When the barb-wires 'a' a are first fed diagonally across the strand` `The moment the barbs are severed the coiling heads or shafts K K 'K2wrap the two ends of each'barb inlopposite directions around the fence-wire a. rl`he two eoiling-heads K and K2 have a coiling-inger, ir, at their adjoining ends, and the middle coilinglhead, K,` has a coiling-h'nger, k, at each end, so' that it can lwrapone end of each of thetwo barbs, wrap# ping themv both of vcourse in the same direc- The two left-handcoiling-heads, K and the fence-Wire and hold it stationary while the coding-'heads are wrapping the barbs` around it. This, however, is more easily and perfectly done `by reason of both ends of the barb being simultaneously wrapped in opposite drections by the ceiling-heads.

barbas they are carried around, as shown in Figs. 5 to 8. As the barb is fed or vprojected diagonally across the fence-wire a, and as the barb is held in this diagonal position after being severed until caught bythe fingers/tk of the coiling-heads, it will be wrapped spirally aroundthe fence-wire a. Thecoiling-ingersk are provided with grooves or notches la for the barb to tor lie in, so that as the barb is wrapped laround,` the ends of the barb will be inclined ordrawn from their diagonal to a right-angle direction to the fence-wire a, as shown in Fig. l

7. The distance between the grooves or' shoulders k of two contiguous coilino tin ers which b o g operate lon the same barb should ofcourse be fthe length of the coils on the wire a, or thelon-1 gitudinal distance between the opposite points ofV the same barb. By this means the middle portion ofthe barb will lie diagonallyor spiral- 1 ly across the fence-wire a, while an approximately rightfangle coil around the fence-wirel a will be formed near each extremity of the barb, and the barb-points will project at right- :angles to the fcnce-wire, as described insaid the coi1ingheads, andthey may be,co`nveniently and rigidly held in place by means of ay groove or recess cut inthe inner periphery of the hollow coiling-heads, anda clamp, 7a2, and' Vihile the coil' ing is being done the dies G and H remain some distance from the wire a, so as to be out of the way ofthe coiling-fingers and the ends of the or diagonal therein.

i The coiling-ingers k are` of course preferably made detachable from` screw k3, as shown in Figs. 11 and 13. The right-hand coiling-head. K2, should be provid ed with a stationary or non-revolving guide, 7o K4, for the fence-wire, which may be conveniently attached to and supported by an arfn or bracket, K5, on the frame. The clamps g and 7L are made narrow, as shownin Figs.5 to l0 and 16, so that the ends of the contiguous coilingfingers can come sufficiently close together to properly catch the barb ends and stillnot strike said clamps, which hold the barb and fence-wire as the ceiling is being done.

As will be observed from' Fig. 4, the knives 8o E and E are so located in relation to each other and to the die G that 'when the head descends far enOugh'tO'cut off the barb, the die G is broughtinto or almost into contact with the wire a, so that in this position said die would interfere with the wrapping of the barb around the fence-wire. The parts are located or arranged in this way to prevent the necessity of carrying the knife E much beyond the edge of the fixed knit'eE, as would 9o be the case if the lower end or face of the die G were located farther up on the head F and the head required to descend correspondingly farther to bring the die into operationafterthe coiling is done. To' get the die G, 9 5 therefore, out of the way of the coilingliingers, the head F,after descendingto cut ofi' the barb and to clamp it between the spring-slides g and h, immediately makes'anupward `n1`ovement to raise the die G' out of'the way, the me spring g3 serving to press the slide g' down against the barb and the opposing slide lv. After the coiling is completed the head F'is again forced down by its operating-cam, and the dies Gg H h form thecrimp or kink a2 in 10 the fence-wire. In forming this crimpit will be Aobserved froin'FigsB and 9 that the face of l the die or slide g'projects slightly `beyond the face of the die G, and that the die H projects beyond "the dich. The dies G and H press no against the coils of the barb, while the die g presses against the middle portion `of the barb,

and the die h withdrawing or yielding as the die g descends, the kink or bend a2 'is formed in the' fencefwire a, and at the same time the 115 middle portionof thebarb is pressed down into the hollow of the bend and lies spirallyl After the crimp is thus formed and the barb completed' the heads F and F3 are withdrawnand 'thewire a fed for- 12o ward the distance of two barbs by the feedwheel, `as two barbs are put on at once, and l then the barb-wires a a are' again fed across to`for'm two'inore barbs, 'andso on. `After the crim'p is fornied in the' 'barb the slide gl is `125 drawn up,with the die' G, by means of a springpawl or catch, g5; `pivoted on the head F, en# gaging ak notch or recess, 96, in said slide g, as shown in Fig. 4. As thejheadF ascends,an`d` just before it makes its downstroke to cut off 13o the barbsthe arm of this pawl g5 strikes against a Vfixed stop, gl, on a standard, g8, of the frame and releases the slide g," so `that"its spring g3l may force it down to clamp the barb and fence-wire. The slide g is not retracted with the die G when the head F makes its upward stroke after cutting off the barb, because when the barb is cut off the head F does not descend quite far enough to cause the pawll g5 to catch in the notch or recess in the slide g. Pivoted spring-clamps L L serve to hold the barbwires a' a' stationary and to keep a tension on said wires while allowing them to be fed forward by the feeding device.

M is a trcugh or vessel for holding oil or other liquid, through which the fence-wire is drawn for the purpose of lubricating the wire and rendering its passage through the machine free and easy. A fixed grooved clamp, m, and a movable grooved clamp, m', mounted on this vessel M, serve not only to immerse the wire a in the liquid in the vessel, but also to put or keep a tension upon the wire a during its passage through the machine. AThe movaable clamp m' is supported and operated by a lever, m2, towhich it is attached, and which is pivoted at m3 to the vessel M, and carries on its outer arm a weight, mf. By moving the weight in or out on this arm the tension may be increased or diminished as desired. The coiling-h-eads K and K2 are driven in one direction and the coiling-head K' simultaneously in the opposite direction by meansV of a pivoted segment, N, operated by a cam, N', on the shaft (l, through gear n on the shaft n', which intermeshes with the teeth a2 on the segment, the gears a3 ai a5 on said shaft a' and the gears a6 nl on the coiling-head shafts K K2, which intermesh with said gears ai ai, and the gear 'as on the ceiling-head shaft K', which meshes with an intermediate gear interposed Y between the gears n* and as so as Yto revolve frame A'.

the head K' in the opposite direction from the heads K and K2.

P is a spring having a curved surface or saddle, p, on its end to keep a proper tension on the barbed wire between the barbing devices and the. feed-wheel. The spool, or rather ifs holder, A', is supported on a shaft, O, `journaled on the brackets or arlns O' of the frame, and one end of the shaft is square, so as to cause'the spool A to revolve with it. The spool A" is caused to slide back and forth on the lshaft O, so as to wind the barbed wire evenly on the spool by means of a non-revolving double-threaded hollow sleeve, 0, anda traveler, o', which is mounted upon the spool- The sleeve o is supported on the bracket O. The end of the shaft O, which fits in this sleeve, should be round, if the shaft is made to extend into thesleeve. The shaft O is driven from the shaft B8 by means ofa sprocket-wheel, O2, thereon, and achain leading to the sprocket-wheel O3 on the shaft'f). It should be observed that as the vibration of the segment N communicates a motion rst in one direction and then in the other to the gear a on the shaft a', said gear n is not secured rigidly to said shaft, but fits loosely thereon, and it is connected to said shaft n so as to operate the same in one direction only by means of a ratchet, n, secured rigidly to the shaft n', and apawl, nl", pivoted to the collar n, which is secured to a sleeve on which the gear n is xed. The barb-wires on'l pass through guides s..
